biotracks 0.5.0

Data package representation for cell migration tracking data

Biotracks provides a standard format for cell migration tracking files and a series of converters from popular tracking sofware packages to the biotracks format, which is a specialization of the Frictionless Tabular Data Package .

Installation from sources (Python 3 only)

python setup.py install

Installation from PiPy

pip install biotracks

Usage

Move to the scripts directory and run:

python create_dpkg.py your_tracking_file

This will create a tabular data package directory containing:

• a csv file for the objects (e.g., cells)

• a csv file for the links (linear collections of objects)

• the json descriptor file for the data package

The latter will look like this:

            "name": "cmso_objects_table",

                ]
            }
        }
    ]
}

Configuration

Some formats require a configuration file that specifies how to map object IDs, coordinate names, etc. This file must be in the INI format with two sections:

• TOP_LEVEL_INFO: specifies a name for the data package and additional (optional) information

• TRACKING_DATA: specifies how to map information from the source format to the biotracks column headers

You can provide a configuration file by passing it via the -c option to create_dpkg.py; if this option is not set, the script will look for a biotracks.ini file in the same directory as your tracking file; if this is not found, the script will use default names for both the overall package and the column headers.

Example:

[TOP_LEVEL_INFO]
author = the author of the dp
title = a title describing the dp
name = a name for the dp
author_institute = the insitute of the author
author_email = a valid email address

[TRACKING_DATA]
cmso_x_coord = the column name pointing to the x coordinate
cmso_y_coord = the column name pointing to the y coordinate
cmso_z_coord = the column name pointing to the z coordinate
cmso_frame_id = the column name pointing to the frame information
cmso_object_id = the object identifier
cmso_link_id = the link identifier
